What are vertices of a polygon?A vertex is a corner point of a polygon, polyhedron, or other higher-dimensional polytope, formed by the intersection of edges, faces or facets of the object.
The vertices of the polygons are given as B(−2, 2), C(4, −2), D(4, 4) . The polygon is reduced by using a scale factor one fourth. i.e 1/4.
This means that each coordinates of the vertices will be reduced by 4 to give the vertices of the new polygon.
A = (-4,6) , A' = ( -1, 1.5)
B = ( -2,2) B' = ( -0.5, 0.5)
C = ( 4, -2) C' = ( 1, -0.5)
D = ( 4,4) , D' = ( 1, 1)
Therefore the vertices of the new polygon is A′(−1, 1.5), B′(−0.5, 0.5), C′(1, −0.5), D′(1, 1)

What is the equation for the line in slope-intercept form?
Answer: y = 8x
Step-by-step explanation:
The line passes through points (1,8) and (2,16).
Using this, we can first find the slope.
Slope = Δy/Δx = 8/1 = 8
So the slope is 8.
The equation is now
y = 8x + b
Let's use the point (1,8) to find the value of b now.
8 = 8 +b
b = 0
Therefore, y = 8x is the answer.
(you can skip the last step by noticing that the graph passes through the origin)
Answer:
y = 8x
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{8cm}\underline{Slope Formula}\\\\Slope $(m)=\dfrac{y_2-y_1}{x_2-x_1}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.\\\end{minipage}}[/tex]
From inspection of the given graph, two points on the line are:
(0, 0)(2, 16)Substitute the points into the slope formula to find the slope of the line:
[tex]\implies m=\dfrac{16-0}{2-0}=\dfrac{16}{2}=8[/tex]
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
The y-intercept is the y-value of the point where the line crosses the y-axis. From inspection of the given graph, the y-intercept is zero. So b=0.
Substitute the found slope and y-intercept into the slope-intercept formula to create an equation for the line:
[tex]\implies y=8x+0[/tex]
[tex]\implies y=8x[/tex]
Therefore, the equation for the line in slope-intercept form is:
y = 8xWhat is midpoint formula Class 11?
The midpoint formula helps us to find the midpoint of a line given to us on a coordinate system.
The coordinate system in geometry is a plane space in which points are located using paired numerical values called coordinates. It is of two types Cartesian coordinate system and polar coordinate system
The cartesian coordinate system is further divided into majorly two parts i.e., 2-Dimensional and 3- dimensional systems. A 2-D system has 2 axis X and Y whereas a 3-D system has X, Y, and Z axes. The plane is divided into 4 quadrants
The midpoint formula is used to find the center of a line or a figure. It is a mathematical equation used in geometry and economics. On a line from point (x1,y1) to (x2,y2) the midpoint P= (x1+y1)/2 , (x2+y2)/2. It divides the line in a 1:1 ratio.

Which equation represents a line perpendicular to the line with equation 2x + 3y = 12?.
The equation of the line perpendicular to 2x + 3y = 12 will be y = 3x/2 + c where c ∈ R.
The equation of the line given here is 2x + 3y = 12
Now rearranging it to the slope-intercept form we get
3y = -2x + 12
or, y = -2x/3 + 4
Now any 2 lines are perpendicular when the product of their slopes results in -1.
Hence, let the equation of the line perpendicular to the given line be
y = mx + c, where m is the slope of the line and c is the intercept.
Hence,
-2m/3 = -1

A farmer decides to start selling his goats at a constant rate per month. After seven months, he has 280 goats left. After eleven months, he has 224 goats left.
If the farmer plotted a straight line graph of how many goats he had left over time, the slope of the line would be -14.
To find the slope of the line representing the number of goats the farmer has over time, we need to use the formula:
slope = (y2 - y1) / (x2 - x1)Where y2 and y1 are the number of goats the farmer has at the end of two different months, and x2 and x1 are the number of months that have passed since he started selling the goats.
In this case:
y2 = 224 (goats left after 11 months)y1 = 280 (goats left after 7 months)x2 = 11 (months)x1 = 7 (months)So the slope of the line is:
slope = (224 - 280) / (11 - 7)slope = -56 / 4 slope = -14The slope of the line is -14, which means that the number of goats the farmer has decreases by 14 goats per month.
It's important to note that when the value of the slope is negative, it means that the line is going down; this means that the farmer is selling goats at a constant rate.

A geometry student named Mary claims that the two triangles in the diagram below are not similar to one another. She asserts that the ΔABC is not similar to ΔXYZ because triangle XYZ is bigger. Explain why Mary is mistaken in her conclusions about ΔABC and ΔXYZ. In writing your response, be sure to explain the difference between similarity and congruence. Also be sure to include important math concepts such as similarity, proportionality, and corresponding sides.
Mary is mistaken in her conclusion that the two triangles are not similar because size does not determine similarity. Similarity is determined by the proportionality of corresponding sides and the congruence of corresponding angles. Congruence is the equality of all the measures of the corresponding parts of two figures.
In order to determine if two triangles are similar, we must compare the ratios of corresponding sides. If the ratios of corresponding sides are equal, then the triangles are similar. In the diagram, it is not specified what the measures of the sides of the triangles are, so it is not possible to determine if the triangles are similar based on the information given. However, if the ratio of corresponding sides are same, then the triangles are similar.
It is important to note that similarity and congruence are different concepts. Congruence refers to the equality of all measures of corresponding parts of two figures, including side lengths and angles. Similarity refers to the proportionality of corresponding parts, including side lengths and angles. A triangle can be similar to another triangle without being congruent, and congruent triangles are always similar.
In summary, Mary is mistaken because the size of the triangle does not determine similarity, it is determined by the proportionality of corresponding sides and congruence of corresponding angles. Without knowing the measures of the sides of the triangles, it is impossible to determine if the triangles are similar based on the information given.

Width of the pool: _m
Answer:
a) Length of the parking lot: 98 m
b) Width of the pool: 89 m
Step-by-step explanation:
a) The formula for the area of a rectangle is [tex]A=lw[/tex].
We need to evaluate the length. Lets solve for [tex]l.[/tex]
[tex]A=lw[/tex]
Divide both sides of the equation by [tex]w[/tex].
[tex]\frac{A}{w} =l[/tex]
We are given
[tex]A=8428\\w=86[/tex]
Lets evaluate [tex]l[/tex].
[tex]\frac{8428}{86}=l[/tex]
[tex]l=98[/tex]
b) The formula for the perimeter of a rectangle is [tex]P=2l+2w[/tex].
We need to evaluate the width. Lets solve for [tex]w[/tex].
[tex]P=2l+2w[/tex]
Subtract [tex]2l[/tex] from both sides of the equation.
[tex]P-2l=2w[/tex]
Divide each term by 2.
[tex]\frac{P}{2} -\frac{2l}{2} =\frac{2w}{2}[/tex]
Simplify.
[tex]w=\frac{P}{2}-l[/tex]
We are given
[tex]P=376\\l=99[/tex]
Lets evaluate [tex]w[/tex].
[tex]w=\frac{376}{2}-99[/tex]
[tex]w=188-99[/tex]
[tex]w=89[/tex]
Answer:
a) 98m , b) 89m
Step-by-step explanation:
(a) Given,
The area of a rectangular parking lot is 8428 m²width of the parking lot is 86 mTo Find : Length of the Parking lot
Length of a rectangle shape can be derived by the formula,
[tex]l = \frac{A}{w}[/tex]
[tex]l = \frac{8428}{86}[/tex]

Hence , the length of a rectangular parking lot is 98m
(b) Given ,
The perimeter of a rectangular pool is 376 mlength of the pool is 99 mTo Find : The width of the rectangular pool
We take the width as variable 'x'
Now we plug it into the perimeter of a rectangle equation
[tex]376 = 2(99 + x)[/tex]
Using distributive property we,
[tex]376 = 198 + 2x[/tex]
We now flip the equation
[tex]2x + 198 = 376[/tex]
[tex]2x = 376 - 198[/tex] ( Transposing into the right hand side)
[tex]2x = 178[/tex]
[tex]x = \frac{178}{2}[/tex]
[tex]x = 89[/tex][tex]m[/tex]
Hence , the width of the rectangular swimming pool is 89m

Now we can square both sides of that equation, then we will get:
(100 cm)^2 = (1m)^2
10,000 cm^2 = 1m^2
Then if we have a measure in square centimeters, to transform it into square meters we need to divide that measure by 10,000.

Write a quadratic equation in standard form that has an axis of symmetry of x=-2and y intercept of 0,6
The quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.
A quadratic equation in standard form is of the form ax² + bx + c, where a, b, and c are constants.
The axis of symmetry of a quadratic equation is given by the line x = -b/2a, so if the axis of symmetry is x=-2, we can set -b/2a = -2, which gives b = 4a.
To find the y-intercept of the quadratic equation, we can set x = 0 and substitute that into the equation: y = a(0)² + b(0) + c = c
So, if the y-intercept is (0,6) then c = 6.
By using above two information, we can write the quadratic equation in standard form as:
a(x+2)² + 4a(x+2) + 6 =0
=> a(x²+4x+4) + 6 = 0
=> a(x²+4x+4) = -6
=> a(x²+4x+4) = -6
=> x² + 4x + 4 = -6/a
=> x² + 4x + 4 = -6/a +10
=> x² + 4x - 6 = 0
So, the quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.

The first step is to equalize the form of the equation.
y = 6x-11 = -6x+y= -11
-2x-3y = -7
thus becoming:
-6x+y= -11
-2x-3y = -7
Then eliminate x:
-2x-3y = -7 | multiplied by 3| becomes -6x-9y=-21
-6x+y= -11
-6x-9y=-21
x in the equation can be eliminated to become:
10y=10
y=-10/10
y=1

Rewrite 5 square root 3^4 as an expression with a rational exponent. Then mark this number on the graph of f (x) = 3^x. Explain how you know where to place it.
Step-by-step explanation:
the nth root of something can be expressed as 1/n as exponent.
e.g. sqrt(2) = 2^(1/2).
so, the 5th root of 3⁴ = 3^(4/5)
for f(x) = 3^x
that means that x = 4/5 = 0.8.
so, I go on the x-axis to the right to 0.8, and from there straight up to the actual curve.
that is the desired point.
Solving a Mixed-Degree
Consider the following system of equations:
10 + y = 5x + x2
5x + y = 1
The first equation is an equation of a
The second equation is an equation of a
What are the solutions of the system?
Answer:
The solutions are:
(1,-4), and (-11,56)
Step-by-step explanation:
10 + y = 5x + x^2
5x + y = 1
Rearrange both equations to isolate y:
y = x^2 + 5x - 10
y = -5x+1
Since y=y, we set set the right sides of both equations equal to each other:
-5x+1 = x^2 + 5x - 10
Rearrange
-x^2 - 10x + 11 = 0
x^2 +10x - 11 = 0
Factor
(x+11)(x-1) = 0
x = -11 and 1
Use these two values of x to find y. We'll use the simpler equation of
y = -5x+1.
x _y
1 -4 (1,-4)
-11 56 (-11,56)
